' DETACABLE" CAN BPOUT.

Application led June 5,

,To all 'whom t may concern.' v f p l Be it known that I', WALTERIL.WHITE- ysions, a citizen of the United. States, residing at Lon Beach,in the county of Los Angeles an State of California, have inventedcertain new and useful Improvements in a Detachable Can Spout.; and dodeclare `the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art tolwhich itappertains to make and use the saine.

'lihis invention relates to an improved detachable spout which isespecially, but not necessarily, designed for use on milk cans.

rThe principal object of the invention is to provide a vspout which isdesigned to extend. through one side of the can with its inner endpositioned in the air space, the s out being formed with a port by meansof w ich the liquid passes into it, and serving to simultaneously permitthe discharge of milk and the entrance of air into the vacuum space forinsuring a steady How of milk when the can is tilted in the usual way.

More specifically speaking, it is another object of the invention ytodevise a spout ,which is in the form of substantially L- shaped tube,the short reach being designed to pass through the top of the can andthe long` reach being adapted for parallel disposition beneath thetop),` the last named reach being equip ed wit a point to penet tratethe top of t e can and with a cutter orcutting the material to providean opening for passa e of the short reach.

Another object offthe invention is-to def vise a spoilt which is such indesign that it class by providing one o Cso utilizes the material forcedinwardl when the spout pierces it for assisting in oldi-ng the spout inplace.

A still further object of the invention is to generally improve uponspouts of this extreme-simplicity and durability which is practical,easy to install and remove, entirely sanitary, and oom- -parativelinexpensive to both the manufacturer an the user.

Other' objects'and advantages of the invention will be apparent duringthe course of the' following description.

, Figure 9 is a detail ing the manner in w ich the -material cut fromthe can top is forced laterally and inward in one piece.

Broadly, the invention comprises a hollow taken on the -tube which hasits inner end pointed land provided with a cutter to pierce the top orthe side of a can, this inner end being adaptum or air space in the cantoV relieve the vvacuum when the can is tilted to permit free `flow ofthe liquid into the tube through i of the can `adjacent the openingthrough .which the tube passes.

The material which is curled inwardly as the spout is forced through thecan exerts a slight spring tension against .the tube and maintains theshoulder in effective engagement with the can to prevent'accidentaldisplacement of the tube and at the same time binds the exteriorlydisposed .packing and stop iiange against the can to insure againstescape of the liquid. A

Specifically described, the improved spout comprises a substantiallyL-shaped conduit or tube, the long reach 1 of which is adapted to extendinto the can C so as to permit it to2 be positioned in spacedparallelism with respect to the to .The long reach 1 is of -alength toexten linto close spaced relation with one side of the can to permit itto extend beyond the liquid level and into the space S to admit air into.this space. This inner end is beveled or diagonally cut as pprspectiveview showed, as before stated, to extend into the vacui Sti tilted todispense a indicated at 2 andis equipped' with a sharpened and pointedsubstantially V-shaped enlargement or cutter 3 which serves tosimultaneously pierce the can top and cut the material. The short reach4 of the tube is designed to extend through the opening O formed in thetop of the can C. At the juncture of two reaches, a comparatively smallport 5 is formed and this serves to permit liquid to entery and be'discharged from the tube. The port 5` is smaller in diameter than thedischargeend of the tube to prevent this end from becoming filled whenthe can is tilted, which would otherwise occur if the port was the sameor a greater area than the cross-sectional area of the tube. Adjacentthis port i5 is a substantially V-shaped locking lug or shoulder 6 whichis designed to bear against the inner side of the top of the can whenthe spout is in place. It maybe conveniently mentioned here that as thespout is forced through the top of the can and manipulated to assume theapproximate position shown in Figures 3 to 7 the material M which isforced inwardly, is curled substantially as shown and this serves toexert a slight spring tension against the long reach 1 and in so doingforces the shoulder 6 in tight contact with the ltop of the can. t alsohas a tendency to bind the packing 7 tightly between the can and thestop flange 8. At its free end, the short reach 4 ofthe tube isfiattened somewhat as indicated at 9 and is provided withV an opening 10in which the hook 11 carried by the nger-piecei12 of a closing cap 13 ispositioned. Normally, this cap 13 is closed and in order to open it, thefinger is placed' against the finger-piece 12 to force it against thefiattened art 9 of the tube. It is of course unessentia to have theclosing cap arranged at the o'int shown and in some instances it may depositioned at a diametrically opposite point so that it willautomatically open when the can is part of the contents.

In order to ienable the reader to obtain I a clear understanding of themannerof4 ining o is thus formed and the material is' stalling the imroved spout, attention is first directed to igure 1. As shown in thisfigure, the long reach of the tube is disposed at substantial rightanglesto the top of the can and the' ointed cutter 3 is forced thru thetop at t e approximate place shown.

large opening and a small `l/-shaped openforced inwardly. Then, thespout is manipulated in a manner to bring the shoulder 6 overthe openingO in the. top of the can so that it can ass thru this vo ning to permitit to be rought against t e underf side o f the can to It is suggestedafter the shoulder tpasses thru the small V-shaped opening 1o t en graspthe spout and turn it a part of a revolution toward the right 'todispose the shoulder 6 beneath the solid part of the can top. Then, thespout is in operative position as shown in Figure 6. With the spout inplace, it is obvious that by tilting the can in the usual way as shownlin Figure 7, the liquid will enter the tube through the small port 5. Ttis to be stated here that this port is of a size to retard the dischargeof the fluid so as to permit it from entirely filling the tube. Hence, asmall space. is left between the fluid and the tube to permit air toenter from the outside and pass throughthe tube into the vacuum space S.Consequently, a steady flow of the fluid is thus insured. l By carefullyconsidering theA description in connection with the drawings, personsfamiliar with devices of this class will doubtless be able to obtain aclear understanding of the invention. more lengthy and detailed deemedunnecessary.

Since probably the best results may be obtained with the constructionand arrangement herein shown and described, this is taken as thepreferred embodiment of the invention. However, I wish it to beunderstood that minor changes comin within the scopel of the inventionas claime may be resorted to if desired.
